The invention relates to building constructions ing one part in theassembly of several of the and more especially to pressed steelstructural framing and method of joining the same.

-The primary object of the invention is the provision of a constructionof this character,

wherein the said metal framing members are of hollow formation and areprecut at the factory so that the same may be assembled at the place oferection of the building or the like without requiring labor in thecutting of said membersfor proper assembly thereof, these members beinginterlocked at the point of use thereof'in a novel manner and arecomposed of a plurality of units adapted for interfltting with eachother.

Another object of the invention is; the provision of a construction ofthis character, wherein the units of .the framing members are assembledand locked together in a novel manner without the use of nails or thelike and create a rigid unitary formation, being precut as per plans ofa structure so that the work or the labor re quired in thefleld wouldmerely be assembly.

A further object of the invention is the pro-.

vision of a construction of this character, wherein lathing, wallfacings, sheathing material may be readily and easily fastened to theframing without the use of nails or other like fasteners and the framingbeing devoid of wood thus being of fireproof characteristic.

A still further object of the invention is th provision of aconstructionof this character, wherein the framing is of hollow sheet metalformation and in the assembly thereof for the erection of an edificewill he possessed of maximum strength and durability, being susceptibleof reinforcement through the use of cementitious or homogeneousmaterial.

Astill further object of the invention is the pro ision of aconstruction of this character, wherein evolves a novel method of thejoining of the units in their assembly to expedite erection of anedifice possessed of maximum strength and longevity.

with these and other objects in view, the invention consists in thefeatures of construction,

Referring to the drawings in detail, particularly Figures 1 to 5inclusive, each framing member constituting the present inventioncomprises pairs of web and flange units It! and H, respectively, eachmade of pressed steel and of hollow formation, -being precut for .mereassembly work in the field after shipment or distribution from themanufacturer. The units l0, each has the reversely beveled outer areasor portions l2 at one side thereof and an intermediate countersunkoutwardly bulged area or portion 13, respectively, so that when thesesides match with each other with the areas or portions 13 making medialcontact with each other, there will be presented therebetweensubstantially arrowhead-like gaps or seats I A opening outwardlytransversely with respect td-the units In and approach the intermediateareas or portions I3 of. said units.

The flange units II at the inner sides I5 thereof,'each has medially ofits inner side I 5 and longitudinally thereof a countersunk arrowheadshaped coupling rib l6 while created at opposite sides thereof are thechannels or grooves ll,

these being adapted to accommodate the longer opposite edges of theunits In with the ribs fitting the gaps or seats I4 between said unitsIII in the assembly of the framing with the result that these units willbe interlocked with each other to efiect a substantial eye stud, joist,beam or other supporting member denoted generally at A. i

To effect a three-way stud construction B, the assembly thereof is hadby arranging a group of three eye studs, beams, joists or othersupporting members-A as shown in Figure 3 of the drawings and connectingthese by hollow substantially triangular shaped connector strips orforms I8 which are welded or otherwise made fast to confronting sidesIII. of the units next thereto and at right angles to each other when apair of the members A are arranged in spaced parallelism with each otherand another of these members intermediate with respect to the latter anddisposed crosswise in its lay thereto.

To efiect a double eye" beam, stud, joist or other supporting member C,a unit 2| of hollow formation having the contracted intermediate portion22 and the outer portions 23, respectively,'

is created, these being in association with the units 24 and the units25, respectively. The units 24 and 25 are similar to the units In and IIand the assembly of these with the unit 2| being shown in Figure 4 ofthe drawings.

To effect the creation of a corner structure -D, a series of membersinvolving the units 26 and 21, respectively, are employed, these beingsimilar to the units I0 and I I and their assembly,-

and are connected together by the strips or forms 28 and 23,respectively, these being welded or otherwise made fast in the joinderthereof with the units 21 next thereto as is clearly shown in I Figure 5of the drawings.

In Figure 6 of the drawings there is shown a portion of a door jamb 3Ufitted in a. framing E involving a pair of sheet metal hollow units 3Iformed with jaw extensions 32 and the arrowhead shaped locking ribs 33,respectively, the jaws being engageable with the unit 34 while the ribs-33 interlock with the latter and a hollow retaining strip 35,respectively, which conceals between it and the unit 34 a filler strip36 having welded or otherwise made fast thereto, bolt-receiving nuts 31for fastening bolts 33 securing the strip in place, a-portion of thedoor being indicated at 39 fitting the jamb 3II.

In Figures 7 and 8 of thedrawings there is shown a window sash or frameassembly F involving the units 40 and 4I,-. respectively, these beingsimilar to the units 33 and 34, the retaining strip being indicated at42 in the window frame at 43, respectively, this having a packing strip44 associated therewith, the filler stri 45 being fastened at 46 and thestrip 42 fastened at 41, respectively.

In Figure 9 01 the drawings there is shownvertical and horizontalsupports'as employed in building construction and each support involvesthe member A including the units I0 and I I, these interlocked with eachother for the eye beam, joist orthe like formation, a portion of thevertical support being indicated at 48 while a portion of the horizontalsupportis indicated at 49. About the support 4l is a cap member in theform of a sleeve'having the instruck portions 5| so that the cap in itsformation will snugly embrace the support 43. The instmck portions SIcarry lips 32 interfitting the horizontal support 43 while at oppositeends of the cap 50 are bendable wings 53 which are disposed by bendingin overlapped relation to the horizontal support 49 and both the saidends of the cap 50 and the cars 53, respectively, each has a clearancefor accommodating a wedge-shaped locking key or fastener 54, it havingburrs or latching nibs and 56, respectively, for the retention of thefastener 54 in place. The supports 43 and 43, each carries preformedslot formations 51 therein, these being initially partly cut into theunits I 0 and I I so that they can subsequently be cleared foraccommodating the keys or fasteners 54 for the joining of the supp ts 48and 49 together.

The units I0 and II, after assembly thereof witheach other, can be.reinforced by fillings of cementitious material, the hollow formationsof such units being receptive of such material.

With reference to Figure 6 of the drawings, the lamb 30 is susceptibleof reversal for the setting thereof with respect to the door 33 shouldit swing outwardly or inwardly in the hanging of such door.

It ispreferable that the, filler strip as be ms- 1 site ends and in theuse of such cap are bent from this position to overlapping joining part.

The keys or fasteners 54 can be used; for attaching to the framing metal.lathing, wall or ceiling facings and sheathing or the like, theserelation to an adkeys or fasteners 54 being bendable'into clinching orgripping engagement with the latter at theirends exposed and projectedbeyond the frame.

In the use of .the invention in its novel sectional construction, it iscustomary to apply a mastic of low heat conductivity in the nature of athin film between its sections and in this fashion lessen theconcentration of moisture and thus add to the usefulness of theinvention. This mastic of low heat conductivity is located between thecontacting surfaces of the web and flange section wherever necessary.

It is further understood that the web and flange section when set up foruse as an I-beam will function as such at any required locality instructural framing and thus offer a solution for insulation and to feeddirect transmission of heat as occurs in the use of steel framing ofmodern trend in building construction. This sectional hollow assemblyhereinbefore set forth eliminates or prevents warping particularly wherethere is great difierences in the temperatures particularly with regardto opposing flanges and a silent movement characteristic is allowed'withrespect to component parts through the elasticity of the mastic filmwhen employed at contacting points of the structure. It is, of course,recognized that cold and heat effects. expansion and contraction ofcomposite parts of steel or metal resulting in perceptible noises andgroans where the movement of one part over another takes place, thisbeing produced through mechanical friction and by the presence ofthe'mastic film between adjacent or at contacting points of the partsthe mechanical friction or movement of these parts is silenced.
